High current SSPC - [Weikewei] - power density increased by 30%

These high-power solid-state power controllers(SSPC)The module is designed to operate with minimal loss and dissipate heat/airflow. They have an independent casing, simplifying the installation process. The high current bus terminal is used to provide a good low voltage drop interface for high current input/output. They are solid-state relays based on microcontrollers, with a rated current of up to 150A, designed for high reliability 28V DC applications. These modules integrate current sensing function and will not lower the rated temperature range throughout the entire operation process. These modules are electronically equivalent to independent control and status of electromechanical circuit breakers. This series offers two SSPC rated currents of 150A and 130A.
